【摘要】 我国是一个多湖泊的国家,湖泊主要分布在五大湖区。据统计,面积在1km~2以上的湖泊近2300个,湖泊面积为71787km~2,约占全国总面积8‰左右。据计算,湖水贮量为7088亿m~3,其中淡水贮量为2261亿m~3。湖泊水量在地区上分布不均匀,年内和年际间的变化也大。因此,要注意湖泊水量的合理利用,对已出现的问题应妥善解决。更多还原

【Abstract】 This paper mainly deals with water quantities of China’s lakes. China is a country with a large number of lakes mainly scattered over five lakes districts. Preliminary statistics shows that China has about 2300 lakes with an area larger than 1 km2. The total area amounts to 71787 km2, covering about 0.8% of the total area of the whole country. By calculations, the storage capacity of lakes is 708,800 million m3, in which the fresh water amounts to 226,100 million. The water quantities of lakes are not evenly distributed in the regions. Their variations within a year and between years are great. So attention should be paid to the rational utilization of water quantities of the lakes. The problems that have already brought up need careful and skillful deliberation.更多还原
